22” Tire Pressure - What PSI are you using?

[JayceeP]

Hey guys- just curious what PSI everyone runs?

I have the gloss black 22” wheels with Michelin Defender LTX.

I know spec is 35 PSI but does anyone go higher? I’m currently at 36.5-37 cold.

Biggest concern is keeping outer edge tire wear in sync with the rest of the tread. I know over inflating can cause middle tread wear but I’ve never seen it happen on any of my trucks or SUV’s…

I run Nitto's on mine and whether it is the stock tires or the Nitto's I run 35PSI,

You have to really overinflated for the tread to wear in the middle.

My 3500 wants the rear wheels at 80psi. They wear in the middle but I can’t find a good medium. If I run 50-60 then the sidewalls bulge like they’re low on air. If I run 70-80 the middles bald. I guess that’s the price of running an HD vehicle

My Yukon with 22s I fill right under 40 and never have any uneven balding issues.

When I purchased my Michelin Defenders, I call Michelin Tech Support and asked them about their recommended tire pressure. They told me to use the tire pressure recommended by GM for my truck. So far, no tire wear issues.

Run what it says on the door

I'm pretty sure the door calls for 36 lbs cold.

Edit: Just double-checked, and that's what mine says.

Not that it’s a big difference but I have a Yukon XL SLT and my door spec is 35 PSI.

Yeah, the weight diff of the XL must matter.

I also run the ltx I run them 2 psi higher than the door. On two tahoes Currently 38 psi on the factory 22” wheel.
I also get pretty good mpg on my unmodified 23/24 Tahoes
Sometimes 23/25mpg highway.

255/70R18, 40pSI cold.

I just noticed the Michelin Defenders LTX m/s have a max rated tire pressure of 44 psi. I’m surprised is that low given the door sticker recommends 35 psi. Anyway, I’m currently at 36.5 cold. Hitting the highway tomorrow and it’s going to be warm by local standards and will be 28C/82F so I’ll be keeping a close eye on how high my tire pressure rises due to both highway speeds (should see 2-3 psi increase) and temp increase as the morning temps rise (probably another 2 psi for that as well). Doesn’t leave a lot of buffer.

That max pressure is cold psi so I wouldn't worry about it.

Thanks for sharing. I wasn’t 100% sure on that!

I would always hate when I had a recall on my truck, 16 ram 2500, that the door sticker says 80 psi for the rear tires. Every time the dealer would air them back up to 80. They're load range e and max 80 psi. I'd immediately lower them back down to 50 when I got home.
